General Motors has been pushing the Volt for well over a year as sales continue to rise and fall depending on the month. In March of 2012, GM suspended production of the Volt due to weak demand. Production of the Volt was started back up in April of 2012, earlier than expected, thanks to an uptick in demand for the extended range electric vehicle.

General Motors has now announced that in June 2012 it sold 1,760 Volts, which is double what it sold in June 2011. So far in 2012 General Motors the sold 8,817 Volts, which adds up to more than three times the 2,745 Volts that it sold in the same period of 2011. In fact, so far in 2012 GM has sold more Volts than in all of 2011. Total Volts sales in 2011 were roughly 7,600 units.

Compared to the Volt, sales of the Nissan Leaf plummeted 69% for June to 535 units. Nissan has only been able to sell 3,418 Leaf EV's so far in 2012, a decline of 19% over the same period 2011.

Nissan maintains that will sell 20,000 Leaf EVs in the US this year, but that seems far-fetched. Nissan would need to sell 2763 Leafs each month for the remainder of the year, which is more of the vehicles than Nissan has sold all year.

Incorrect. Volt can run at full speed (up to a governed 100mph) solely on its primary electric drive motor. The only time the genset can engage with the wheels is when the battery's state of charge goes below its minimum level (the 'battery' gauge on the dashboard is at 0%, but the battery's charge is more like 30%) while the car's being driven at highway speeds.

The reason for this is that spinning the the ring gear makes the final ratio taller so it behaves as an upshift, so that the primary motor can spin more slowly and more efficiently. When there's adequate charge in the battery, the ring gear is powered by the motor/generator attached to the gas engine (but it's declutched from the gas engine at that time). Only when the state of charge is too low and the Volt is at highway speeds does the ring gear run while it's clutched to the gas engine. This is done because not doing so is less efficient, and GM has engineers, not whiny petulant fanboys who don't actually care about efficiency.

You really should do some more research before you spout off uninformed BS.
